Does the Red Hat Ceph Storage Manager API handle `chunked` transfer encoding requests?

Issue

• Reaching the Ceph Manager API endpoint with the chunked transfer encoding set fails with the error 411: Lenght required:

  curl -X POST "https://$MGR/api/auth" -H  "accept: application/vnd.ceph.api.v1.0+json" -H  "Content-Type: application/json" -d "{"username":"admin","password":"mysecretpassword"}" -H "Transfer-Encoding: chunked"
  
  {"status": "411 Length Required", "detail": "Client must specify Content-Length", "request_id": "9f093c4a-73e2-4b81-8ebf-284424fbbeeb"}
  

• The same request works as expected when the length is set:

  curl -X POST "https://$MGR/api/auth" -H  "accept: application/vnd.ceph.api.v1.0+json" -H  "Content-Type: application/json" -d '{"username":"admin","password":"mysecretpassword"}' -H "Content-Length: 50"
  

• Why is this so? Does the Ceph Manager API support this transfer encoding?
